The first strength - equipps elaborately made dual-layer fan blades cooling system to increase airflow and air pressure which provides greatly increased cooling efficiency. At present, the general use of graphics on the combination of ordinary fans and heat sinks to remove heat from GPU. However, the average fan design constraints of the effective radiating area, so that heat dissipation area is limited to the external heat sink, while in most in need of cooling, and GPU core part of the formation of a thermal blind spots.

Now, Calibre X240/X240G graphics cards dual-layer fan cooling system uses two-tier design, will be two different colors, different levels of blades into a single body, compared with the single-layer fan blades, can produce an unusually strong the amount of wind pressure and wind, bringing double cooling efficiency, cooling fan to eliminate the traditional graphics generated by thermal blind spots.

The Second Strength - Extend the Blades Length to 9 cm, 1cm Longer Than Ordinary Fans' Blades, Bringing More Powerful Air Pressure.
The Calibre X240/X240G features longer fan blades and larger airflow and air pressure. The fan diameter of the Calibre dual-layer fan blades cooling system is 9cm, 1cm longer than the ordinary diameter of heatsink/fan combination.

The Third Strength - Reversely Rotate 30 Seconds To Effectively Remove The Dust Inside The Fan
The Calibre dual-layer fan blades cooling system can act as clean expert for the Calibre X240/X240G graphics cards. When the computer starts, in the first 30 seconds, the fan will rotate clockwise. After 30 seconds, it will rotate anticlockwise. The purpose is to use the powerful of the dual-layer fans to take the dust away from the internal parts of the cooling system, to prevent dust accumulation, making the graphics card even more clean and tidy and improving the sanitary conditions inside the chassis to extend the graphics card's life. The onboard red/green LED lights remind the user of the fan working condition, the red light means the fan rotates anticlockwise, the green light means the fan rotates clockwise.

Interesting, I read that anticlockwise is the british way of saying counterclockwise.
And that the jews used to have clocks that rotated the other way because they also read/wrtite the other direction, so I guess you could call it jewishclockwise :)

Anyway for the yanks the term is counterclockwise, abbreviated CCW.
Maybe they should make updated PR material for the US regions.

We use reversible fans in certain applications to self clean. They work well, but do have more working parts, and thus failures. Is this really needed on a card of this size? Do you really want to hear the fans spin up and down every 30 seconds?

I had to check twice as well, but I believe they mean the first 30 seconds after booting your PC the fan spins counterclockwise, and after that it does its normal job.

I don't see it as being effective as they claim it would be to clean out the dust. Sure it'll work a little bit, but most electronics attract dust off of electrostatic forces. Slowly but surely that will build up over time regardless of the fan direction since it's still using electricity. I could be wrong, I'm just kind of working off the physics that I have taken crossed with a bit of life experience which is always deadly, but I think that they're overhyping the idea.

by: WarEagleAUSo what does this mean for performance? I had no idea it was a GT 240 type card either. Seems pretty useless to me. However, that is MY OPINION.

Its really not the point "Why the card?" but whats the point with the elaborate cooling solution?I mean it could almost run passively with no need of a active cooler but Sparkle seems to think it was worth the PR money to come up with some dual rotor "anti-clockwise" cooling solution......what the hell for?

Looks like another. "We are bored and not selling cards so lets brain storm some gimmicks to help sell these outdated video cards we have stock piles of"

This is interesting, I remember doing tests quite a while ago with several fans stacked(different speeds, different diams) but never thought to try mounting the blades like this. I wonder how the noise/air flow compared to a reg 90mm fan?

At first when I looked at this I thought 2 separate spinning fans but after closer looking the 2 fans are attached together making 1 blade.

I dont get the reverse spinning thing though, 30sec isant gonna remove a significant amount of dust, that seems like adding complexity where it isant needed (marketing baloney)
